  • Manufacturer Part No 1B22AN

Product Overview

The 1B22AN is an isolated Voltage-to-Current Converter that incorporates transformer isolation to achieve high performance and automated surface mount manufacturing for low cost and increased reliability. Functionally, the V/I converter consists of four basic sections input conditioning, modulator/demodulator, isolated loop supply and current source. This is pin programmable for 0V to +5V or 0V to +10V inputs and 0 to 20mA or 4 to 20mA outputs using an internal resistor network. It can also be set by an external resistor to accept 0V to +1V to 0V to +10V inputs. Transformer coupling provides 1500Vrms galvanic isolation between the inputs and the current loop. Loop power is generated internally through a DC/DC converter and is also isolated from the input side (1500Vrms). Loop compliance voltage is dependent on the voltage supplied to the converter and with VLOOP is equal to 28V, it is sufficient to drive a 1000Ω load.
